HUMIiJIFIER.

Application filed March 14, 1925. Serial No. 15,685.

This invention relates toimprovements in humidifiers for use in connection with in ternal combustion enginesiand has torits principal object to provide a simple and etiicient device for supplying moistened air,

to the carburetor whereby the efliciency oi the operation of the internal combustion en sumption of fuel.

ii. still'further object is provide afhu inidilier or" the above mentioned character which will operate automatically, thus insuring the supply ofa proper amount of moistened air to the carbureter, means. being provided for preventing any possibility of ater entering the carbureter.

A still further object is to provide a hun'iiditier oi? the above mentioned character which may be readily and easily attached with the several parts of an automobile with which the device is associated without necessitating any material alterations of said parts.

A still further object is to provide a humidifier of the above mentioned character which will at all times be positive and etficient in its operation, which is further simple in construction, inexpensive, and furthermore adapted to the purposes for which the same isdesignated. I v d Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is an elevational view of the huniidilier embodying my invention showing the same connected up for use with an internal combustion engine.

Fig. 2 is an enlarged elevational view of the casing with parts broken away and illustrating the valve arranged in the casing, and

Fig. 3 is a transverse section taken approximately 011 the line 3-3 of Fig. 2.

In the drawing wherein for the purpose of illustration is shown the preferred embodi ment of my invention, the numeral 1 designates a substantially cylindrical casing, the same being provided with an apertured ear 2 at its top for attaching the casing to the core of the radiator 3 of an automobile on the inside thereof as clearly illustrated in Fig. 1.

An overflow pipe t extends from the top of the radiator into the top of the cylindrical casing liso that the moistened air and steam generated in the top of the radiator willbe discharged into the casing. A steam outlet pipeb communicates at one end witlrthe casing 1 at a point adjacent the top thereof through'the medium of a suitable fitting illustrated at 6. The opposite end ot the pipe 5 communicates with the air intake of the 6b earbureter 7 of the internal combustion engine generally designated by the numeral 8. A water outletpipe 9 extends downwardly from the bottom of the casing, thesame havmg communication therewith through the medium of a fitting 10. Arran'ged within the casing 1 at the lower portion thereof is the horizontally extending plate or disk 11, the sainebeingprovided with an openinglil.

A flap valve 13 fashioned from the punch- 7 ing of plate 11 to form the opening 12 normally closes the opening 12 and this valve is pivotally supported on the plate or disk 11 as illustrated at 14:. An axle coiled spring 15 is associated with the pivot pin 14: and

provides a means for normally holding the valve 13 in its closed position. The purpose of the valve will be certainly apparent.

1th the parts arranged as shown in F 1g.

1, the vapor formed in the top of the radiator a large amount of moistened air will be supplied to the internal combustion engine and as the throttle is gradually closed, the sup ply of moistened air to the carbureter is gradually decreased.

In order to prevent any possibility of the water which may overflow from the radiator and enter the casing 1 through the pipe 4:, being admitted to the carbureter, the valve 1.3 will open under the weight of the water so that the water will flow outwardly from the casing 1 through the outlet pipe 9. The valve 13 will automatically return to its closed position when all of the water has been discharged from the casing so that the moistened air and steam will not escape n;

out through the pipe 9, thus assuring the supplying of the moistened air to the'carbureter through the pipe 5.

A humidifier of the. above mentioned character will at all times be positive and emcient in carrying out the purpose for which it is designated and the simplicity in which the device is constructed enables the'same to be readily and easily installed upon an automobile and will not in "any way interfere with the usual operation thereof.

Byadn'iitting a supply ofmoistenedair to the carbureter, the consumption of fuel will i be reduced to a minimum and furthermore ing, whereby the latter is divided into a relatively large upper moistened 'air'coinpartment, and a relatively small water compartment in the lower portion of the casing, a moistened air discharge pipe extending from the side of the upper portion of the moistened air compartment, a water discharge pipe extending from the closed lower end of the cylinder and communicating with the water compartment, said plate beingprovided with an enlarged central opening by punching out the central'portion thereof, a flap valve fashioned from said punched out portion pivotally associated with the plate and cooperating with the opening, resilient means for normally holding the valvein a closed position, said flap valve adapted to be actuated by the weight of the waterentering the casing from the steam inlet pipe to permit the water to be discharged from the moistened air compartment into the water compartment, and out through the water discharge pipe, the flap valve normally preventing the moistened air from entering the water compartment.

In testimony whereof I affix my signature.
